Was this machine or Cardiologist who did reading. The one who knows you best can best interpret. Not likely the machine, :-) Dr humor.

Non-specific T wave abnormality is common and its significance is often unclear unless accompanied by a history and other findings suggestive of a heart problem. It is not clear why you the ECG done. My advice to you is not to be alarmed BUT have your doctor evaluate you with a detailed history including family history, examination etc. Unlikely heart disease but get the opinion.
